Changi Water Reclamation Plant Fit for the Next Century

With a pumping station that is 25 stories tall, the Changi Water Reclamation Plant, located on the diamond-shaped island of Singapore

, is the cornerstone of the Singapore Deep Water Sewage System. This system is responsible for purifying wastewater for consumption throughout the City/State of Singapore. The NEWater plant, which went online last summer, produces 50 million gallons of treated water daily. That’s the equivalent of 90 Olympic –sized swimming pools.

"The designers have incorporated a space saving design concept - things like stack treatment tanks and also stack treatment facilities like our sludge treatment facilities. All the treatment facilities are stacked on top of the other so as to save space," said Yong Wei Hin, assistant director of Changi Water Reclamation Plant.
Such a concept is the first in the world.

This monumental project needed low maintenance costs, real-time communication, with remote diagnostics and needed to be integrated with an already existing asset management system. Due to mandatory connectivity requirements, it was decided to use PROFIBUS DP V1 as the protocol for communication. This complicated matters since both Schneider Electric and Rockwell Automation PLCs were both used in the plant.

Schneider Electric contacted ProSoft Technology to allow the PLCs to communicate with PROFIBUS DP. With the PROFIBUS integration via 160 ProSoft Technology PROFIBUS DP V1 Quantum modules, the plant’s overall system architecture now provides high-speed communication as well as power to devices over the bus, making it possible to have very large networks.

The addition of the PROFIBUS DP V1 module to ProSoft’s ProTalk line of Quantum modules has helped Schneider Electric open a new avenue of communication possibilities.

"Schneider Electric is very strong in the process industry and wanted to bring valuable solutions with PROFIBUS and FDT/DTM technology," said Ken Roslan, Strategic Marketing Manager for ProSoft Technology. "We were able to help them expedite time-to-market and get the customer acceptance and final buy-in."

The PTQ-PDPMV1 functions as a PROFIBUS DPV1 Master. Developed upon Quantum backplane transfer technology the protocol module sends information back and forth through the Quantum processor. It collects all the necessary information on the configured PROFIBUS DP network. Built on Siemens ASIC ASPC2 Step E with Infineon C165 Microprocessor, the module’s Firmware is flash-upgradeable, and allows for slave messaging, extended diagnostics and alarm handling, and notification, and more.

The Changi Water Reclamation Plant has been operating successfully since June 2009.
